Privacy and cookies

Our use of your data, cookies, and external services: what you should know, and how to opt out if you want to.

Summary: We care a lot about our users’ privacy. We provide details below, and we try our hardest to look after the private data that we hold. Like many other websites, we sometimes use cookies and Google Analytics to help us make our websites better. These tools are very common and used by many other sites, but they do have privacy implications, and as a charity concerned with socially positive uses of the internet, we think it’s important to explain them in full. If you don’t want to share your browsing activities on mySociety’s sites with other companies, you can adjust your usage or install opt-out browser plugins.


This is our privacy policy (sorry it is so long, but it is quite precise):

  • We will pass on your message, name, email and postal address and (optionally) telephone number either direct to the politician(s) you write to, or to a trusted intermediary (such as a council democratic services department) who will then pass it on.
  • We will never sell or otherwise distribute any information you give WriteToThem to organisations or individuals outside of mySociety, except in the following circumstances:
    • when required to do so by UK law;
    • if you come to the site via, we are given a unique ID that we pass back to them when you confirm your message. If you were logged in to, they will know you have sent a message (but nothing else).
  • We will store your IP address and the pages that you visited whilst on the site as part of our site logs. We keep these for one month.
  • We will never keep permanent copies of the letters you write to send to your representatives, and will not look at your messages unless there is a problem with the operation of the site which requires us to do so.
  • We will store the content of your message for four weeks after it was dispatched. Then it is automatically deleted. We keep a copy in backup files for one additional week. We need to keep it for this long to monitor and prevent abuse of the service. It also means we can include a copy of your message in the email which asks if your representative has responded yet.
  • If delivery of a message fails for a week, we keep the message content for a further 8 weeks. This gives us time to diagnose the problem. We sometimes need the content so we can resend the message.
  • We keep records of names and addresses for longer periods in order to provide an audit trail if a representative queries the accuracy of the statistics on response rates we produce. We will never give these out to a representative on any other occasion than when you send them your message.
  • If you contact mySociety via our support email address we reserve the right to keep your support message indefinitely, especially if you say something nice about us.
  • We use cookies to track how people use mySociety sites, and how they move between them. We do this only to make our sites work better, and we will never give away the data that we collect in this way.
  • We will never send you unsolicited email except:
    a) One survey email and up to one reminder two weeks after you send your message.
    b) In the rare case that a politician asks us to pass a message on their behalf to survey respondents in their constituency/ward who say they have not heard back from them.


To make our service easier or more useful, we sometimes place small data files on your computer or mobile phone, known as cookies; many websites do this. We use this information to measure how people use the website so we can improve it and make sure it works properly. Below, we give more information on which cookies we use.

Measuring website usage (Google Analytics)

We use Google Analytics to collect information about how people use this site. We do this to make sure it’s meeting its users’ needs and to understand how we could do it better.

Google Analytics stores information such as what pages you visit, how long you are on the site, how you got here, what you click on, and information about your web browser.

IP addresses are masked (only a portion is stored) and personal information is only reported in aggregate.

We have also enabled the Advertising Features of Google Analytics. In particular, we use Demographics and Interest reporting to identify trends in the types of users visiting our site, which may be used for internal reporting and improvement of the site content.

In technical speak, this allows Google to collect data about your traffic via Google advertising cookies and anonymous identifiers, in addition to data collected through a standard Google Analytics implementation. Regardless of the source of the data, we strictly adhere to Google’s policy requirements in our treatment of your data. We do not facilitate the merging of personally-identifiable information with non-personally identifiable information collected through any Google advertising product or feature. We do not allow Google to use or share our analytics data for any purpose besides providing us with analytics information.

Opting out

If you’re unhappy with the idea of sharing the fact you visited our site (and any other sites) with Google, you can install the official browser plugin for blocking Google Analytics.

If you want to disable advertising-based tracking, you can adjust your Google Ads Settings, or opt out of advertising-based tracking across a number of providers in one go using the Network Advertising Initiative’s opt-out form.

Email Opt-Out

As part of the process of sending your message to your representative we will send you a limited number of emails as described here. If during this process you wish to stop receiving emails from us, or you are a representative who no longer wishes to receive email via WriteToThem, please contact us at
